It’s quite possible that your cooling fans electrical harness or the relay is faulty; which most likely triggered this warning code to illuminate on your dash. Although your car is not currently overheating, failure to repair this issue may eventually cause this to occur; which can cause serious mechanical damage. It’s a good idea for you to have a professional mechanic complete a check engine light inspection, so they can download all the stored error codes that triggered this warning light; determine what is broken and make the right repair recommendations to solve this issue.
